The world wide web is like a global filing system that runs on the internet. Each entry in this filing system is a website, which can consist of many webpages. Each webpage brings code, text, and multimedia files together. Hyperlinks are special interconnections between webpages that help users navigate through the world wide web.
As the internet grew it became difficult to find information. Data was stored in a tree structure, the way files are stored on personal computer. In 1989, English engineer Tim Berners-Lee (b. 1955) came up with a solution to flatten the tree by making related files link to each other with clickable hyperlinks. This meant that to find something, users could simply jump from one relevant document to the next, instead of backtracking through a maze of folders.
